This avoids the accidental symbol # conflict. # # However, in some cases, we build an external module to provide a # different version/variant of the in-kernel module, overriding the # same set of exported symbols. # # At least, there is one use-case in the upstream code; # tools/testing/nvdimm/libnvdimm.ko replaces drivers/nvdimm/libnvdimm.ko # in order to link it against mocked version of core kernel symbols. # # Now, this emits a lots of 'exported twice' warnings: # # https://lkml.org/lkml/2019/10/31/627 # # To suppress those, add a new option KBUILD_MULTI_EXPORT_NO_WARN. # # If you intentionally override the existing symbols, you can pass it # from the command line: # # make M=tools/testing/nvdimm KBUILD_MULTI_EXPORT_NO_WARN=1 # # Or, more conveniently, you can add it to the module Makefile, so # you can still do: # # make M=tools/testing/nvdimm # # without sprinkling the warnings. # # Reported-by: Jeff Moyer <jmoyer@redhat.com> # Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> # Tested-by: Jeff Moyer <jmoyer@redhat.com> # < /opt/cross/kisskb/gcc-4.6.3-nolibc/s390x-linux/bin/s390x-linux-gcc --version # < /opt/cross/kisskb/gcc-4.6.3-nolibc/s390x-linux/bin/s390x-linux-ld --version # < git log --format=%s --max-count=1 aa9581108f498991e309c4a90b1af0805d2e41b5 # < make -s -j 48 ARCH=s390 O=/kisskb/build/kbuild_s390-defconfig_s390x CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/s390x-linux/bin/s390x-linux- defconfig # make -s -j 48 ARCH=s390 O=/kisskb/build/kbuild_s390-defconfig_s390x CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/s390x-linux/bin/s390x-linux- cc1: error: unrecognized command line option '-mtune=zEC12' cc1: error: unrecognized command line option '-mtune=zEC12' make[2]: * [/kisskb/src/scripts/Makefile.build:99: scripts/mod/devicetable-offsets.s] Error 1 make[2]: * Waiting for unfinished jobs.... make[2]: * [/kisskb/src/scripts/Makefile.build:266: scripts/mod/empty.o] Error 1 make[1]: * [/kisskb/src/Makefile:1109: prepare0] Error 2 make: *** [Makefile:179: sub-make] Error 2 Command 'make -s -j 48 ARCH=s390 O=/kisskb/build/kbuild_s390-defconfig_s390x CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/s390x-linux/bin/s390x-linux- ' returned non-zero exit status 2 # rm -rf /kisskb/build/kbuild_s390-defconfig_s390x # Build took: 0:00:03.260442
